My guess is as long as GB tries to shortchange Berto, we probably won't be seeing this fight take place before the year is over. Dibella has seemingly been scouring the earth to find a suitable payday for Berto so a challenge to Campbell wouldn't entirely be shocking. Unlikely though.
Good fight for Mosley, going after an undefeated young gun in the division... i think berto can do better then some think in this fight, though i have to go with mosley winning a decision, i would love to see Mosley win that fight then go on to maybe fight clottey, mayweather, cotto 2, margarito 2, pac perhaps... lot of good fights out there for mosley.
Obvious fight for Shane (if he'd just read the writing on the wall), but I could easily see Berto's people driving a bargain GBP doesn't accept. I think it's alright for him though. He could rebound from a loss fine; if he makes a decent showing, it wouldn't hurt him much. The Collazo rematch would always be there for him and would attract decent interest.
